Incidence, Sideslip, & Airspeed

Calculate angle of attack, glide angle and airspeed.

incidence sideslip airspeed

Description

The Incidence, Sideslip, & Airspeed block calculates the angles between the velocity vector and the body , and the total airspeed from the velocity component in the coordinate system associated with the body.

The block uses the following equations for the calculation:

The formula for calculating uses to avoid division by 0.

Ports

Input

Vb is the velocity of the body
`vector 3 to 1

The velocity of the body given as a 3 by 1 vector recalculated in a coordinate system relative to the body.
